Income inequality and self-reported values

What is the relationship between income inequality and the values people endorse? Using survey data from all thirty-four OECD countries over a period of almost thirty years, we investigate the following dimensions of value systems: work ethic, civism, obedience, honesty, altruism, and tolerance. In most cases, no robust relation to income inequality is detected. However, we find some evidence that larger income disparities are associated with a stronger work ethic. This suggests that income inequality might spur hard work not only through pecuniary incentives but also because it makes people attach a symbolic value to being laborious.     

The impact of testosterone replacement therapy on glycemic control,vascular function,and components of the metabolic syndrome in obese hypogonadal men with type 2 diabetes

Objective: This study set out to assess effects of testosterone replacement therapy (TRT) on parameters of metabolic syndrome and vascular function in obese hypogonadal males with type 2 diabetes mellitus (DM2).

Study design: Fifty-five obese hypogonadal diabetic males on oral hypoglycemic treatment were enrolled into this one-year, double-blind, randomized, placebo-controlled clinical study. Group T (n?=?28) was treated with testosterone undecanoate (1000?mg i.m. every 10?weeks) while group P (n?=?27) received placebo.

Methods: Anthropometrical and vascular measurements – flow-mediated dilatation (FMD) and intima media thickness (IMT) – biochemical and hormonal blood sample analyses were performed at the start of the study and after one year. Derived parameters (BMI, HOMA-IR, calculated free testosterone (cFT) and bioavailable testosterone (BT)) were calculated.

Results: TRT resulted in reduction of HOMA-IR by 4.64?±?4.25 (p?p?p?=?.005).

Conclusion: TRT normalized serum testosterone levels, improved glycemic control and endothelial function while exerting no ill effects on the study population.     

Das TIMP-Inventar – Ein Beitrag zur ökonomischen Erfassung von Kern-Faktoren salutogener Führung

Occupational health management and science increasingly focus on the issue of health-promoting leadership. Meanwhile a lot of leadership behaviors have been identified that affect the health of employees. To measure them requires high costs. Therefore, the aim of this study is to identify core-factors of salutogenic leadership and to operationalize them for an efficient diagnosis. As an integrative work-related indicator of employees’ health sense of work coherence (Work-SoC) was chosen. In a deductive and inductive process the TIMP-inventory has been developed that enables the economic assessment of three leadership dimensions: Trust, Incident Management and Pressure. These factors explain with less items more variance of the Work-SoC construct than established general and health-related leadership scales of transformational leadership, consideration, social support, demanding leadership as well as positive and negative health behavior. That is why the TIMP-factors can be recognized as core-factors of health-promoting leadership.     

CONGLOMERATES AND REGULATION

Conglomerates operating integrated productions in different regulated and unregulated sectors may benefit of scope economies. However, the precise size of these synergies is often unknown to both rival firms and regulators. We show that the conglomerate's private information on scope economies may negatively affect both the regulated and the unregulated sectors depending on the precise nature of competition (strategic substitutes or complements). We also unveil a novel effect of regulation that involves an informational externality to the conglomerate's rivals. Notwithstanding these complications, and independently of the nature of competition, we show that in our model it is desirable, as for welfare, to let the firm run integrated productions, unless diseconomies of scope may realize.

The role of the board in shaping foundations’ strategy: an empirical study

This paper investigates the relationships of the choice of philanthropic strategy with board capital (diversity and networks), board activities (board processes, internal board committees, and board effectiveness), and CEO leadership. Using a sample of 110 Italian foundations, the research shows that board processes have the strongest positive association with an evolved strategic approach to philanthropic institutional grant-giving, while board diversity and strong CEO leadership are associated with the strategic approach only under certain conditions. In particular, good governance processes (e.g., training the board, self-evaluation of trustees, setting the stage for effective board and committee meetings, implementing control software, and steering meetings to improve the board’s analysis) are positively associated with evolved strategic approaches to philanthropy (e.g., signaling other funders for the best grantees, improving the performance of grant recipients, and advancing selected social fields’ state of knowledge and practice).     

Bat boxes in urban non-native forests: a popular practice that should be reconsidered

Impact mitigation practices are currently one of the hottest topics in conservation and regarded as priorities worldwide. Forest bat populations are known to provide important ecosystem services such as pest control and bat boxes have become one of the most popular management options for counteracting the loss of roosts. However, bat boxes tend to be employed in non-native forests near highly humanized areas where human disturbance is higher. The aim of this study was to evaluate how the surrounding landscape composition affects bat box occupancy in urban non-native forests along the Mediterranean corridor in the Northeastern Iberian Peninsula. Two hundred wooden bat boxes were monitored in young non-native forests in the period 2004–2012. The influence of land cover on occupancy rate of bat boxes was analysed at the landscape level in a 5 km buffer around bat-box stations. In total, 1659 inspections were carried out, in which a 15 % occupancy rate was detected. Bat boxes hosted three different species (Pipistrellus pygmaeus, Pipistrellus kuhlii and Nyctalus leisleri). More than 70 % of the occupancy can be explained by habitat and spatial composition. The presence of urban areas around bat boxes tends to have a negative impact on bat occupation rates; by contrast, forest coverage has a positive effect, especially for the tree-dwelling bats. These patterns could be associated with the large number of available roosts in buildings, microhabitat or phylopatry. Thus, to increase success, we suggest that landscape composition should be considered when using bat boxes for conservation.     

A level playing field for migrant entrepreneurs? The legal and policy landscape across EU and OECD countries

Migrant entrepreneurship has been recognized as a form of integration in the country of destination and a viable alternative of decent and sustainable employment for migrants. Laws and policies can create barriers or support migrants who start a business in the country of destination. Despite their importance, these laws and policies have received scant attention from academic scholarship. By applying the mixed embedded approach, this article analyses the institutional and policy framework for migrant entrepreneurs in European Union (EU) and Organisation for Economic Cooperation and Development (OECD) countries, and how this framework varies according to the migrants’ individual legal status and gender. In order to do so, this article draws upon the findings of two different studies conducted on the topic. The first one analyses the national institutional framework for migrant entrepreneurs of these countries. The second study consists of a review of measures to foster migrant entrepreneurship in the same sample of countries. On the one hand, this article shows that the institutional framework restricts access to self-employment for some categories of migrants (e.g. based on their legal status). On the other hand, a wide range of measures are now available to support migrant entrepreneurs. However, these measures treat them as a rather homogeneous group. These findings suggest that the fact that some migrants are less engaged in self-employment or face more difficulties may be explained by the lack of institutional opportunities and policy support.     

Drivers of Change in the Democratic Republic of Congo: The Role of China in Re-Shaping the Country

Africa has always been potentially one of the richest continents in the world, but, due to a series of causes (colonization and decolonization process, wars, dictatorships etc.) it has never reached its full potential. The fight against poverty has been carried out by different institutions at the multilateral and bilateral level during the last 30 years, but the route toward economic development seems to be still long for African countries. This paper will focus on the analysis of the new approach to international cooperation introduced by the People’s Republic of China in order to exchange rights of exploitation of Africa’s mining and natural resources with large amounts of capital without any conditionality. The case-study which will be considered is the agreement concluded between the People’s Republic of China and the Democratic Republic of Congo.     

Comparing aggregate and disaggregate forecasts of first order moving average models

This paper compares the performance of “aggregate” and “disaggregate” predictors in forecasting contemporaneously aggregated vector MA(1) processes. The necessary and sufficient condition for the equality of mean squared errors associated with the two competing predictors is provided in the bivariate MA(1) case. Furthermore, it is argued that the condition of equality of predictors as stated by Lütkepohl (Forecasting aggregated vector ARMA processes, Springer, Berlin, 1987) is only sufficient (not necessary) for the equality of mean squared errors. Finally, it is shown that the equality of forecasting accuracy for the two predictors can be achieved using specific assumptions on the parameters of the vector MA(1) structure.
